UniApp Vue3: 'uni-page-body' Not Found Error - Quick Fix

This error occurs when you are trying to use the 'uni-page-body' component in your UniApp project but it cannot be found.

To resolve this issue, you need to make sure that you have installed the '@dcloudio/uni-ui' package in your project. You can do this by running the following command in your project directory:

npm install @dcloudio/uni-ui

After installing the package, you need to import the 'uni-page-body' component in your page or component file. You can do this by adding the following code:

import { uniPageBody } from '@dcloudio/uni-ui';

Once you have imported the component, you can use it in your template by adding the following code:

<uni-page-body>
  <!-- your content here -->
</uni-page-body>

This should resolve the issue and allow you to use the 'uni-page-body' component in your UniApp project.
